I-O2 Sensor Signal Circuit Mfushane ku-Heater Bank 1 Inzwa 1

Kusho ukuthini lokhu?

Le yi-generic Diagnostic Trouble Code (DTC) esebenza ezimotweni eziningi ze-OBD-II (1996 nezintsha). Lokhu kungafaka kepha akukhawulelwe ku-VW, Kia, Peugeot, BMW, Cadillac, Holden, Honda, Ford, njll. Naphezu kwemvelo ejwayelekile, izinyathelo eziqondile zokulungisa zingahluka ngokuya ngonyaka wokwenziwa, ukwenziwa, imodeli nokudluliswa.

Ikhodi egciniwe engu-P2231 isho ukuthi imojula yokulawula i-powertrain (PCM) ithole okufushane kunzwa yomoya-mpilo okhuphuka nomfudlana (O2) yenombolo yokuqala yebhange lenjini. Ibhange lokuqala yiqembu lenjini eliqukethe isilinda inombolo eyodwa. Inzwa 1 ikhomba inzwa ekhuphukayo (inzwa yangaphambili) kusistimu yezinzwa ezintathu (ngokungafani nesistimu yezinzwa ezine).

I-PCM isebenzisa okokufaka okuvela kuzinzwa ezishisayo zomoya-mpilo (HO2S) ukuqapha okuqukethwe komoya-mpilo kumagesi okukhipha ebhange ngalinye lenjini, kanye nokusebenza kahle kwesiguquli se-catalytic.

Izinzwa zomoya-mpilo zakhiwa kusetshenziswa i-zirconia sensing element etholakala maphakathi nendlu yensimbi evulekile. Ama-electrode amancane e-platinum athengiswa phakathi kwesici sokuzwa nezintambo kusixhumi se-oxygen sensor harness. Isixhumi sokubopha inzwa ye-O2 sixhuma kunethiwekhi yesilawuli (i-CAN), exhuma ihanisi ye-oxygen sensor kusixhumi se-PCM.

I-HO2S ngayinye inezintambo (noma izikopelo) kwipayipi lokukhipha noma ezininginingi. Ibekwe kahle ukuze into yokuzwa isondele enkabeni yepayipi. Amagesi okukhipha imfucuza ashiya igumbi lokushisa umlilo (ngokusebenzisa izinqwaba ze-exhaust) futhi adlule ohlelweni lokukhipha (kufaka phakathi abaguquli be-catalytic); kuvuza ngaphezu kwezinzwa ze-oxygen. Amagesi okukhipha angena enzwa ye-oksijini ngokusebenzisa imingcele yomoya eyakhiwe ngokukhethekile ezindlini zensimbi futhi azungeze into yensiza. Umoya odonswe ngezimbobo zocingo ezindlini zenzwa ugcwalisa ikamelo elincane maphakathi nenzwa. Umoya oshisayo (egumbini elincane) ubangela ukuthi ama-ioni oksijini akhiqize amandla, i-PCM ewabona njengamandla kagesi.

Umehluko phakathi kwenani lama-O2 ions emoyeni ozungezile kanye nenombolo yama-molecule e-oksijini ekuqothulweni kubangela ukuthi i-oksijeni ions evuthayo ngaphakathi kwe-HO2S igxume ngokushesha okukhulu futhi ngezikhathi ezithile kusuka kolunye ungqimba lweplathinamu kuye kolandelayo. Njengoba i-ions ye-oksijini eshayayo ihamba phakathi kwezendlalelo zeplatinamu, amandla wokukhipha we-HO2S ayashintsha. I-PCM ibona lezi zinguquko kumandla wokukhipha we-HO2S njengezinguquko ekugxileni kwe-oksijini kugesi wokukhipha.

Imiphumela yamandla kagesi evela ku-HO2S iphansi lapho umoya-mpilo omningi ukhona ku-exhaust (isimo esinciphile) futhi uphakama lapho umoya-mpilo omncane ukhona ku-exhaust (state rich). Le ngxenye ye-HO2S isebenzisa i-voltage ephansi (ngaphansi kwe-volt eyodwa).

Engxenyeni ehlukile yenzwa, i-HO2S ishiswa kusetshenziswa i-voltage yebhethri (ama-volts ayi-12). Lapho izinga lokushisa lenjini liphansi, i-voltage yebhethri ishisa i-HO2S ukuze iqale ukuqapha i-oksijini ekuqothulweni ngokushesha okukhulu.

Uma i-PCM ithola izinga levolthi elingekho ngaphakathi kwemingcele eyamukelekayo, i-P2231 izogcinwa futhi ilambu le-Malfunction Indicator (MIL) lingakhanyisa. Izimoto eziningi zizodinga imijikelezo eminingi yokushisa (ekuhlulekeni) ukuvula ilambu lesixwayiso.

Inzwa ye-oxygen ejwayelekile:

Buyini ubunzima bale DTC?

Ukujikeleza okufushane ku-HO2S kungaholela ekusebenzeni kabi kwezinjini nasezinkinga zokuphatha ezahlukahlukene. Ikhodi ye-P2231 kufanele ihlukaniswe njengobucayi futhi ilungiswe ngokushesha okukhulu.

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenkinga ye-P2231 zingafaka:

• Ukwehla kwamandla kaphethiloli
• Ukunciphisa ukusebenza kwenjini
• Amakhodi Okugcwala Agciniwe noma Amakhodi Wokukhipha Ocebile / Acebile
• Isibani senjini yensiza sizokhanyisa kungekudala

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi zingabandakanya:

• Inzwa / s oksijini enamaphutha
• Izintambo ezishisiwe, eziphukile, eziphukile noma ezinqanyuliwe kanye / noma izixhumi
• Iphutha lokuhlela le-PCM noma le-PCM elingalungile

Yiziphi ezinye zezinyathelo zokuxazulula inkinga nge-P2231?

Ukuxilongwa okunembile kwekhodi ye-P2231 kudinga isithwebuli sokuxilonga, i-digital volt / ohmmeter (i-DVOM), nomthombo wolwazi wemoto onokwethenjelwa.

Xhuma isithwebuli esikhumulweni semoto sokuxilonga bese uthola wonke amakhodi agciniwe kanye nedatha yoqhwa ehambisanayo. Uzofuna ukubhala lolu lwazi phansi uma kwenzeka ikhodi ivele ibe ngephakathi. Bese usule amakhodi bese uhlola ukushayela imoto. Ngalesi sikhathi, eyodwa yezinto ezimbili izokwenzeka. Kungaba i-P2231 izosulwa noma i-PCM izongena kumodi elungele.

Uma ikhodi iphakathi futhi i-PCM ingena kumodi elungile, kungaba nzima kakhulu ukuyithola. Izimo eziholele ekugcinweni kwe-P2231 zingadinga ukuba zimbi kakhulu ngaphambi kokuthola ukuxilongwa okunembile. Uma ikhodi isuliwe, qhubeka nokuxilonga.

Ukubukwa kwe-faceplate yesixhumi, imidwebo ye-pinout pinout, ukwakheka kwezinto, imidwebo ye-wiring, nemidwebo ye-diagnostic block (ehlobene nekhodi ehambisanayo nemoto) ingatholakala kusetshenziswa umthombo wolwazi lwemoto yakho.

Hlola ngokubonakalayo izintambo nezixhumi ezihlobene ne-HO2S. Faka esikhundleni izintambo ezisikiwe, ezishisiwe noma ezilimele.

Uma ikhodi ye-P2231 iqhubeka nokusetha kabusha, qala injini. Yivumele ifudumale ize ifinyelele kokushisa okujwayelekile kokusebenza futhi ingenzi lutho (ngokuhanjiswa kungathathi hlangothi noma epaki). Xhuma isithwebuli esikhumulweni semoto sokuxilonga bese ubona okokufaka kwe-oxygen sensor ekusakazweni kwedatha. Nciphisa ukusakazwa kwedatha yakho ukufaka idatha efanelekile yempendulo esheshayo.

Uma izinzwa zomoya-mpilo zisebenza ngokujwayelekile, amandla omoya onqenqemeni lwezinzwa zomoya-mpilo umfutho wokuguqula okuguqukayo azojikeleza ngokuqhubekayo kusuka ku-1 kuye ku-900 millivolts lapho i-PCM ingena kumodi evaliwe yeluphu. Izinzwa zePost-Cat nazo zizohamba phakathi kuka-1 no-900 millivolts, kepha zizofakwa endaweni ethile futhi zihlale zizinzile (uma kuqhathaniswa nezinzwa zangaphambi kwekati). I-HO2S engasebenzi kahle kufanele ibhekwe njengengalungile uma injini isebenza kahle.

Uma i-HO2S ibonisa umbane wamandla webhethri noma ingekho i-voltage ekusakazweni kwedatha yesithwebuli, sebenzisa i-DVOM ukuthola idatha yesikhathi sangempela kusixhumi se-HO2S. Uma okukhiphayo kuhlala kufana, sola ukufinyelelwa kwangaphakathi kwe-HO2S okuzodinga ukushintshwa.

• Ezimweni eziningi, uzolungisa le khodi ngokufaka ama-HO2S afanele, kepha uqedele ukuxilongwa noma kunjalo.
